This application is a continuation-impart of my application for Valve construction, filed March 18, 1941, bearing Serial' No. 383,905', now Patent No. 2,335,685, granted November 23, 1943.

-Referring irst to` Figures and 6, the valve preferably consists of a casing,.generally indicated' at I9, having a distributorv plug, generally indi'- cated at I2, rotatably mounted therein. Plug I2', which' directs and controls the flow of gas or other fluid through the valve,y is rotatedV by a handle I3. This valve which isparticularly adapted for controlling the flow of gas to a mul-` tiple-ring gas burner; generally indicated at I4, (Figure 7), has an inlet port I5' (Figure 5) and a series of outlet ports I6, II, I8, t9, and 2li..A The outlet ports are connected by pipes. I'G'a, I'Ia, IBa,

Illa, and 2ila'(-Figure 7) tothe rings'ZE.. 21, 28519,!

and` 30 of burner Ill. By adjusting distributor plug I2, any individual outlet port may be connected to thev inlet port and the degreev of flow of gas tothe selected port may be varied` between open and closed'V positions. Furthermore; the outlet ports beginning; with port I6 may be connected successively.` to the inlet port until they are all connected in unison to' the inlet port and then th'e outlet ports may be successively closed beginning with port I6 by Vcontinued.y rotation. of the distributor plug. The degreeof ow of gasi to any group of outlet ports may be varied between open'l and closed positions;

Referring to Figure1 6, casing I0 has a bore I Iiextending downwardly therein. This bore has'a tapered side wall which forms. a seat for the tapered. side wall of distributor plug I2.' Thus, the tapered side wall' of the bore forms a bearing surfacefor the distributor plug, permitting rotation of. the-'plug within the casing-.l The open end of bore I' I` is covered by a cap ZI which is provided with Ythreads complementary to threads on casingv I 0, permitting it to be screwed into position thereon. The'stem 22` of plugf'I12 extends upwardly through a hole 23` (Figure 6) in cap 2|v` and handle I3 is secured to stem. 22 in any suitable manner. HandleV I3 isA providedVr witha linger l3ntl which when used in conjunction with index markings (not shown) on the t'op surface of cap 2l enables the user of the valve to setthe distributor plugin any desired position. A spring 24 mounted on stem 22 exerts resilient pressure between cap 2l and th'e upper surface of plug I`2 tohold th'e plug seated inbore I I The inlet and outlet ports in the casing are internally threaded to permit the attachment of the main gas supply to the` inlet' port I5 and the connection of each of'the outlet ports to a ring. of th'e multiple-ring gas burner. Y. in Figure 6, the outlet ports I6, I1, It; I9, and 2KB and inletport'l5 are positioned in'a horizontal plane substantially in the center of the side wall of casing Ill. The mouth of inlet port I5 (Figure 5) is enlarged so'that it extends a substantial distance around the side wall of the casing in both directions,A andv themouths ofthe inlet and outlet ports arefpositioned onv substantially` opposite sides-of the casing. n

A passageway, generally indicated at 6I), which extends diametrically across plug I2,v is usedto connect the mouths of the inlet and outlet Vports. This passageway has an enlarged mouth Signat one endand extends through the distributorpluvg in a horizontal plane with' its ends Yin alignment witlfrtl-lemouthsV of the inlet and outlet ports. A

As is best shownY series of closure members 521, 53, 54, and 55 are positioned in enlarged mouth` 6I adjacent bore .I I dividingthat end of passageway 60 into a serles of passages 32, 33, 34, 35, and 36. The width of i the outer ends of the closure members is slightly greater than the diameter of the mouths of outlet ports I6, I1, I8, I9, and 20, and all of the closure members are of the same width. All of the mouths of outlet ports I6, I1, I8, I9, andr are of the same size and are spaced from each other by distances equal to the width of the outer .Y

ends of the closure members.

cessively supplied with gas and the amount of gas being supplied to a series of ports may be For purposes to be disclosed more fully here-l inafter, the passage 32 and passageway 6I) from.

passage 32 to mouth 33 at its other end, although of the same Width as the mouths of passages, 35, 36, and 31, are oval shaped andV have the same depth as the mouth I5a (Figure 6) of inlet port I5. This substantially increases the quantity of gas available to passages 34, 35, and 36'whenever fpassage 32 or mouth 33 is connected to the mouth I5a of inlet port I5.

By setting the distributor plug indiiierent positions gas may be supplied to any single outlet port or to a series of outlet ports. In Figurel distributor plug I2 has been turned in a counterclockwise direction from a shut-01T position so that mouth 33 of passageway 60 is connected to outlet port I6. As the distributor plug continues to move in a counterclockwise direction, full con` nection between mouth 33 and port I6 is attained after which the size of the opening between the two is reduced until mouth 33 is positioned between ports I6 and I1. During this time'gas is entering passageway 60 through passages 35, 36, andk 31 from the mouth |511 of port I5. VBy continuing counterclockwise movement varied .between open and closed positions. Furthermore, all. of the outlet ports may be opened of the distributor plug, mouth 33 ymay be connected toV any of the outlet ports and the degree of the connection may be varied between open andclosed positions. InV Figure 2 mouth 33 is shown positioned between ports I1 and I 8 ina closed position. Thus each ring of the burner may be individualy supplied with gas and the degree of flow of gas may be varied between fully open and closed positions.

In Figure 3 the valve is shown in a "shut-off position after the connection between the mouth 33 of passageway 60 and outlet port 20 has been closed. Next by continued rotation of the distributor plug in a counterclockwise direction, the mouths of passages 31, 36, 35, 34, and 32 are consecutively brought into connection with outlet port I6. As the mouth of each passage passes beyond the mouth of outlet port I6, the passage mouth is closed and continued counterclockwise rotation causes it to connect with the following outlet port I1 (Figure 4). Thus, the outlet ports may be consecutively connected (Figure 4) to the mouths of passages 31, 36, 35,` 34, and 32 in the distributor plug. In every case, before another outlet port is added to the series to which gas is `being supplied, the mouths of the passages 32, 34, 35, 36, and 31 are shut olf (Figure 5). As counterclockwise movement is continued from the position shown in Figure 4, the outlet ports are successively connected to and then shut oil from the mouths of passages 31, 36, 35, 34, and 32,- the connections between a series of outlet ports and plug pass ges opening and closing in unison. Y

As plug I2 is rotated in a counterclockwise direction from the position shown in Figure 4, the enlarged mouth of passage 32 (Figure 6) described hereinabove insures a sufficient supply successively-and then closed successively so that a' -variety of different combinations of the rings of the burner may be operated at one time. Also, any individual burner may be used and the amount of gas supplied to this burner may be varied between open and closed positions.

Referringto Figure 8 in which another embodiment of the valve described hereinabove is shown, the valve, generally indicated at I (lo, is substantially the same as the valve shown in Figures 11-6 with the exception that in the present embodiment the outer ends of closure members 52a, 53a, 54a, and 55a'are smaller than the width of the outlet ports 20a, I 9a, I8u, Ila, and I6a,'and the mouths of passages 32a, 34a, 35a, 36a, and 31a, and mouth 33a are wider than the portions of casing I0 separating the outlet ports. Thus,-asthe distributor plug I 2a of this valve is rotated to connect the mouths of passageway 60a tothe outlet ports, gas is'not completely shut oi at any time from the outlet ports by the closure members and mouth 33a supplies two outletports at the 'same time as it is moving from' one outlet port to another. This eliminates the necessity of re-igniting the rings of a burner each time a new ring is added to the series to which gas is being supplied or when mouth 33a ismoved from one outlet port to another. As in the valve shown in'Figures l-B, there are two positions of plug I2a at which all 'gas is cut oi from the outlet ports.

A further variation of'either the valve shown in-Figures 1-6 or the valve shown in Figure 8 is achieved by forming interconnecting passages 10, 1I, 12, and 13 (Figure 8) extending through the portions of casing I0 separating the outlet ports and thus interconnecting the outlet ports. With this type of construction when gas is supplied to one of the outlet ports, it immediately is fed to the others through the interconnecting passages. The passages are small so that each burner burns with a very low flame unless it is connected to one of the mouths of passage 6U. This type of construction also eliminates re-ignition of the burners whenever a change is made in the setting of either plug I2 or I 2a.

It might be pointed out here that the valves described hereinabove may be used to direct the ow of liquids and furthermore that if this valve is used as a mixing valve, the ports specied as outlet ports hereinabove may be used as the inlet ports of the vvalve and the inlet port used as the outlet port. Thus, it will be seen that a thoroughly practical and durable valve construction it is to be understood that all matterhereinbefore set forth, or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.
